7272 (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
7273 * c-common.h: Update prototypes.
7274 * c-decl.c (struct c_scope): Update commentary. Remove names,

7282 scope_freelist; initialize scope->depth and check for overflow.
7283 (poplevel): Rename to pop_scope; totally rewritten for new bindings
7285 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
7286 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
7287 Improve some commentary. Adjust handling of forward parm decls.
7288 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
7289 Preserve C_DECL_IN_EXTERNAL_SCOPE.
7290 (warn_if_shadowing): Correct indentation. Improve diagnostics.
7291 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
7292 decls. Rewrite for new bindings structures. Improve commentary.
7293 Eliminate the copy_node call.
7294 (implicit_decl_warning): Use the "diag" idiom (as seen in
7295 locate_old_decl) to reduce code duplication; call locate_old_decl
7296 if appropriate. Relocate to remove need for forward declaration.
7297 (implicitly_declare): Adjust for new bindings structures. Kludge
7298 around Objective-C not-really-builtin functions.

7310 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
7311 First scope pushed is the external scope, not the global scope.

7317 (grokparms): Return 0 if arg_types is error_mark_node.
7318 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
7319 reversed sense. Rewrite for new bindings structures. Do not
7320 leave any decls in the scope, to prevent pop_scope from doing
7321 contradictory things with them.
7322 (finish_struct, finish_enum): Remove redundant diagnostics.
7323 (build_enumerator): Don't cascade diagnostics for error_mark_node.

7355 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
7356 correct loop over multiple translation units; call fatal_error if
7357 requested to compile more than one file at once. (This disables
7358 IMA temporarily - an up-front error being preferable to a crash.)
7359 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
7360 (all actions): Adjust calls to pushlevel/poplevel.
7361 (parsing_iso_function_signature): Delete.
7362 (extdef_1): Fold into extdef.

7371 to suppress -Wold-style-definition after this error.
7372 (c_parse_file): Don't clear the binding stack or call
7373 finish_fname_decls here. Correct comment.
7374 * c-typeck.c (same_translation_unit_p): Export.

12143 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
12144 (_cpp_lex_direct): Use linemap_position_for_column.
12145 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
